Assistant Commissioner Michael Corboy of the state's Traffic & Highway Patrol Command said operations targeting heavy vehicles and dangerous drivers in the Western region will continue to be a focus for police.

"In addition to targeting dangerous drivers, our officers will continue to target those who are using our roads to transport drugs," he said.

"Our dedicated officers who have undertaken CATCH training continue to deliver results for the community in removing drugs off our streets," Assistant Commissioner Corboy said.

Police stopped a number of vehicles on the Queensland and New South Wales border over the weekend.
